3. ערשט סעטאַפּ

3.1 טשאַרדזשינג די מיטל

Before first use, fully charge the oscilloscope. Connect the provided USB data line to the device's charging port and to a 5V/1A, 2A, 3A, or 4A USB power adapter. The built-in 1200mAh lithium battery can be charged continuously for approximately 3 hours.

3.2 קאַנעקטינג די זאָנד

Connect the matching probe to the BNC connector on the top of the oscilloscope. Ensure a secure connection by twisting the probe connector clockwise until it locks into place.

3.3 פּאַוערינג אויף / אַוועק

To power on the device, press and hold the power button (usually located on the side or bottom) for a few seconds until the screen illuminates. To power off, press and hold the power button again until the device shuts down.

4.2 Probe Attenuation Settings

It is critical to match the probe's attenuation setting with the oscilloscope's input setting to ensure accurate measurements.

• פֿאַר 1X measurement (0-40V): Set both the physical switch on the probe and the 1X/10X button on the oscilloscope to the 1X שטעלע.
• פֿאַר 10X measurement (40-800V): Set both the physical switch on the probe and the 1X/10X button on the oscilloscope to the 10X שטעלע.

4.3 Measurement Modes and Triggering

The oscilloscope supports various trigger modes to stabilize waveform display:

• סינגלע: Captures a single waveform event and then stops.
• נאָרמאַל: Captures a waveform only when a trigger condition is met.
• אַוטאָ: Continuously acquires waveforms, even without a trigger, but will trigger if a signal is present.

ניצן די TRIG button and arrow keys to adjust the trigger level, which determines the voltage point at which the oscilloscope begins to acquire data.

4.4 Waveform Storage and Management

The device includes 16MB of built-in storage, capable of storing up to 500 waveform images. Use the file manager function to browse, view, and manage saved waveforms. This includes viewing detailed information, flipping through images, and deleting unwanted files.

5.2 באַטערי קער

To prolong battery life, avoid fully discharging the battery frequently. If storing the device for an extended period, charge it to approximately 50% and recharge every few months.

5.3 סטאָרידזש

Store the oscilloscope in a cool, dry place, away from direct sunlight, extreme temperatures, and high humidity. Keep it protected from dust and physical impact.

6. טראָובלעשאָאָטינג

• Issue: Abnormal measured data.
  לייזונג: Check the probe's attenuation switch (1X or 10X) and ensure it matches the setting on the oscilloscope (using the 1X/10X button). If the probe is set to 10X and the oscilloscope is set to 1X, the device will not be damaged, but the data displayed will be incorrect.
• Issue: Device does not power on.
  לייזונג: Ensure the battery is sufficiently charged. Connect the device to a power source using the USB data line and allow it to charge for at least 30 minutes before attempting to power it on again.
• Issue: Screen is blank or frozen.
  לייזונג: Try performing a soft reset by pressing and holding the power button for an extended period (e.g., 10-15 seconds) until the device powers off, then power it back on. If the issue persists, ensure the battery is charged.
